Hydraulic fracturing pipe with sealing device

The invention relates to a hydraulic fracturing pipe with a sealing device, belonging to the technical field of geotechnical engineering. The device is composed of a hydraulic fracturing pipe body, a lock nut, a pressure cylinder, a pressing plate, a rubber seal ring and a locating nut; the middle section of the hydraulic fracturing pipe body is provided with a hydraulic fracturing section, and the surface of the hydraulic fracturing pipe body is provided with threads; the two ends of the hydraulic fracturing section are orderly provided with the locating nut, the rubber seal ring, the pressing plate, the pressure cylinder and the lock nut respectively from inside to outside; the locating nut and the lock nut are respectively rotatably arranged on the hydraulic fracturing pipe body; the rubber seal ring, the pressing plate and the pressure cylinder respectively movably sleeve the hydraulic fracturing pipe body. The locating nut can adjust the length of the hydraulic fracturing section, the rubber seal ring can achieve the sealing effect. and no stress concentration will be generated; besides, the lock nut can easily lock the hydraulic fracturing pipe body in a sample by the pressing plate and the pressure cylinder. The hydraulic fracturing pipe with the sealing device disclosed by the invention has the advantages of rational design, easy processing and operation, and is capable of saving time and resources and capable of being repeatedly used.
